Most drill presses don't have the power to do it..by the way..

That's why I added a Roots 6V-71 Blower (supercharger) on my Chevy V8-powered drill press. And to think, some people think its to blow away dust! Silly people! Arh-arh-arh!!!

I realise that you will have to return the slotted ones you have Peter for replacement.

Hi Harry

I got some more locally and these had the hex heads. These were cast in some sort of ally, where the originals were cut steel with an interrupted slot. I was amazed at how much easier the hex ones were to drive in and I can understand your comment.

Cheers

I'm pleased about that Peter, it really does make you wonder why slots are still used for anything where a hex will fit. The ones that I use are made from a Zinc type alloy. I wonder if the hex ones have filtered through to the USA yet!!!!!!!!!!!!!

Harry, they are filtering here.

Lance, the reason that I added that comment was because no one else said they had used the hex headed ones so I assumed that they may have been another great Australian invention!!

Hi Harry

They are a very old type in the states,,,once man started to make is own wood,,,most just don't hold well,they like to pull out the norm

many Mfg.like to use them in cheap furniture mfg. but most are using the new type with flange on them now...PB,MDF,ETC.they like to give away with any pulling on the board..many call them sex bolts (male and female fasteners) with a end cap to hide the Allen hex head.. the norm.

I have some in the shop but they are not cheap..but hold well

Bummer Bj, there was I thinking it was another great invention from Australia. I agree that in poor quality MDF they can move under stress so I always use glue which also acts as a lubricant during insertion.

Install with a metric sized hex wrench, or the appropriately sized driver to install. Made in USA
